Riken Raptor ZR215/50ZR17

The Raptor ZR is RIKEN’s Ultra High Performance Summer tire developed for the drivers of sporty coupes and sport sedans looking to combine responsive steering and performance-focused handling in an attractive package. However, like all Ultra High Performance Summer tires, the Raptor ZR is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.

The Raptor ZR molds a summer tread compound into an aggressive, directional tread design focused on providing traction in dry and wet conditions. The arrow-shaped pattern utilizes wide lateral grooves for efficient water evacuation and improved hydroplaning resistance. The tire sidewalls feature a rigid compound to help improve handling and steering response, while a built-in rim protector helps prevent damage to wheels.

Ultra High Performance Summer tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.

Note: Flexing of the specialized rubber compounds used in Ultra High Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.
